Description

Technical Field

[0001] This invention relates to the field of terminal forming technology, and more particularly to a multi-cavity terminal cutting and feeding device. Background Technology

[0002] In the field of precision manufacturing of electronic components, connectors, relays, etc., the automated cutting and feeding of terminals (metal pins) is a key process in the production process.

[0003] Chinese patent CN209452594U discloses an automatic terminal cutting and feeding device. This device transports terminal strips to a cutting mechanism via a terminal feeding mechanism. The cutting mechanism cuts the terminal strips into terminals of appropriate lengths. Then, the distance between the two terminals is adjusted using a distance module to meet the connector's terminal spacing requirements. Finally, a Y2 transport mechanism transports the adjusted terminals to a feeding and positioning module, preparing them for the next process. However, when dealing with multi-cavity products and terminals that are small and irregularly shaped, the transport mechanism struggles to precisely coordinate with the cutting mechanism after cutting, and interference is likely. This results in unsatisfactory accuracy and efficiency.

[0004] Therefore, it is necessary to develop a multi-cavity terminal cutting and feeding device to solve the above problems. Utility Model Content
